I'm not sure how much of this is a question and how much is a vent, so I apologize in advance.

I obsessively watch the timeline on Query Tracker, stupid I know. And it feels like every agent I submit to either skips around a ton (including skipping my query, of course) or just stops responding to queries for a month after getting to mine (I might be exaggerating here). It's driving me nuts! I really just need them to put me out of my misery already.

Can anyone give me some reasons why they might skip around so much?
